Author interpretations and caveats

Paraphrased for this database from the authors’ stated interpretations — never quoted verbatim — and kept separate from reported measurements.

Application RelevanceSupport assessment: High

Cu-MOF/CF functions as a non-enzymatic glucose sensor with short response time, wide linear range, low detection limit, high reported sensitivity, selectivity, stability and serum-sample feasibility.

Caveat: The reported sensitivity unit is printed differently in the main text and SI Table S1, and the SI Table S1 linear-range upper bound (1.45 mM) conflicts with the main text/abstract value (0.95 mM); both are retained with source-specific provenance.

7 · Conclusion · Linked to 13 structured results

CaveatSupport assessment: High

Although current increases at pH 14, oxygen evolution can interfere with glucose detection, so pH 13 was selected.

5 · Electrochemical Characterizations · Figure 3D · Linked to 1 structured result

CaveatSupport assessment: High

The reported Cu-MOF/CF linear detection range is inconsistent between sources: the main text reports 0.001-0.95 mM, while SI Table S1 reports 0.001-1.45 mM.

Caveat: No correction notice is present in the supplied documents; do not harmonise these values without manual review.

Composite RoleSupport assessment: High

The Cu-MOF component provides the glucose oxidation activity, while bare copper foam alone shows no visible redox/catalytic response.

Caveat: The comparison is based on CV under the reported alkaline electrolyte conditions.

Phase AssignmentSupport assessment: High

XPS Cu 2p peaks and satellites indicate Cu2+ in the Cu-MOF.

4 · Material Characterization · Figure 2D · Linked to 3 structured results

Phase AssignmentSupport assessment: High

PXRD confirms that Cu-MOF was successfully synthesised and the powder phase matches expected Cu-HHTP-type reflections.

Caveat: PXRD of Cu-MOF/CF itself was too weak, so powder collected from the reaction system was used for structural confirmation.

4 · Material Characterization · Figure 1C · Linked to 5 structured results

Transport MechanismSupport assessment: Medium

The glucose oxidation process at Cu-MOF/CF is described as diffusion-controlled because peak current density varies linearly with the square root of scan rate.

Caveat: The fitted equation was read from the rendered figure; no full raw current series was available.
